Gem eS dead


I’ve had my 2007 eS for 6 years and the only problem I’ve had is changing all the batteries ~2 years ago. I went to turn it on today and the screen was blank. I plugged it in, nothing. I have checked the master switch and main fuse panel. All OK. I have turned off the master switch for 15 minutes and turned it back on, nothing. Please advise. Thanks.

How long was the GEM sitting since it’s last use? Measure the DC voltage across all six batteries. Then measure each battery and post the results. It is possible something electrical was left on and ran the battery down.
